This is the repository for code examples used in the public AWS documentation. The code examples are organized by programming language. You can also try using the preview of our use case index of examples and let us know what you think about it.
Inside each language-specific directory, we include a README file that explains how to build and run the examples in the directory. The example code in the language-specific directories is organized by the AWS service abbreviation s3 for Amazon S3 examples, and so on.
To propose a new code example for the AWS documentation team to consider working on, create a request. The AWS documentation team wants to produce code examples that cover broader scenarios and use cases, versus simple code snippets that cover only individual API calls. From time to time, the AWS documentation team will select some of these proposals to begin working on.
To view their decisions, see the code examples roadmap. The Wish List represents proposals that the team might begin working on sometime in the future, but with no expected timeline.
The Backlog stage represents proposals that the team will likely begin working on soon. To view the team's progress, see the code examples roadmap.
If you plan to contribute examples for use in the documentation the purpose of this repositoryread this section carefully so that we can work together effectively. For process instructions and additional guidance, see the Guidelines for contributing. Make sure that the code you want to contribute builds and runs.
There's nothing more frustrating in developer documentation than code examples that don't work. Build the code and test it before submitting it! Don't include personal account data, keys, or IDs in your examples. Code should obtain access keys from the standard SDK credentials and config files, use environment variables or external data files, or query the user for this information. Format code lines to 80 characters. Long lines can be enclosed in a scrollable box for HTML, but in a PDF build, long lines often spill off the side of the page, making the code unreadable.
If your code includes long text strings, consider breaking these into smaller chunks and concatenating them. Use short er variable names. To aid in readability and to help keep line length to 80 characters, use short yet descriptive names for variables.
Do not mimic class names when creating variables that represent an object of that class. It nearly always results in excessively long variable names, making it difficult to keep code lines to 80 characters. Use spaces, not tabs, for indentation. Tabs are variable length in most editors, but will usually render as 8 characters wide in printed documentation.

Also, the online resources are not informative so can someone please let me know how to do this or any other better way to do this instead of hard-coding the credentials?
You can do that by creating the file or using aws configure with the cli command, answer the questions and it will generate this file:. I believe this is not supported in the browser.

Those services are accessed via a web management console, which is a web application that allows the management of the AWS services using a rich and interactive UI.
Before we start writing any code, we first need to prepare and configure the environment by creating an app ID in the Web Identity Federation side, create a role, configure permissions for this role in the AWS IAM side console, and assign the app Client ID to the created role to establish the connection between the two parts:.
Once this is complete, click on Role for Identity Provider Access radio button :. Next, select the identity provider from the drop down list and enter the client ID in the audience text input and click on continue:. Take a look to this doc for more details. We can edit the permissions document manually or by using the policy generator and entering the Amazon Resource Name ARN :.
If we compare it with the configuration and deployment of a web app with a backend server, it could be considered a time and money saving process. To load the SDK in the browser, we simply need to add the following script tag:. The getAccessToken function will use the following code to authenticate the web user and get a temporary access to AWS services:.
The serviceUser object should be declared at the top of the page. This object will be used afterwards to authenticate the user in the AWS service. To authenticate our application on the AWS side, we should use the ARN Amazon Resource Name that we have received when preparing the environment, and the serviceUser variable that we filled in the previous section.
The SDK keeps the same methods and properties, making the code migration very simple from server side to client side. For more details about how to create the web identity credentials, take a look at this AWS doc. Finally, and after preparing the environment and configuring the web identity credentials, we can now load the AWS services objects and consume the services from our app.Welcome to our resources for Cognito developers.
Here you'll find technical materials that describe how to accomplish a specific task with code samples you can re-use in your app. The first set of guides below teach you the essentials for Cognito User Pools, Federal Identities and Sync development.
If you're a new to Cognito, you should start from "Creating your first project". Amazon Cognito User Pools makes it easy to create and maintain a user directory and add sign-up user on-boarding and sign-in to your mobile or web application for authentication, authorization, and resource access and control. You can use Amazon Cognito Sync to synchronize user profiles and progress data across devices so users pick up where they left off when they change devices.
With Amazon Cognito Federated Identities you can sign in users through social identity providers such as Facebook and Google or through corporate identity providers with SAML and control access to your backend resources.
